Ardbeg The Ultimate Single Islay Malt Scotch Whisky Limited Edition 21 Year Old, 1999, 42.4%

This lower ABV version was reportedly produced in error and limited to a single batch. Believed to comprise around 204 bottles, it was only sold at the distillery gift shop. A distillery located on the south coast of the Isle of Islay. It is currently part of the Scotch whisky holdings of LVMH. Despite being closed twice in the latter 20th century, the distillery's heavily-peated single malt has a unique character. This specific bottling was supposedly the product of a mistake when the bottling strength was reduced to 42.4% instead of 43%, and was bottled separately from the rest of the 1999 release and sold without a box.
